Tyrannotitan chubutensis Skeletal Diagrams. by Franoys Tyrannotitan chubutensis Skeletal Diagrams. by Franoys
Tyrannotitan is a giant argentinian Carcharodontosaurid, that lived 125-112 million years ago in the Gondwanan continent. It is the most basal and oldest member of Carcharodontosaurinae subfamily, which radiated in Gondwana. It is the closest relative of Carcharodontosaurus . Missing elements were restored after Giganotosaurus and Carcharodontosaurus.

If you use windows you just need to extract from the zip (right click and extract here) and then you should be able to open them with openoffice of microsoft office word. However here is the page in which I downloaded everything;

My dumb ass really expected something like a 13 m long beast with a hip height of nearly 4 meters, because I forgot that we had enough preserved bones to calculate the size as far less than t.rex...

Neat overhaul!
It looks quite unique (not as unique as the short legged one, but it still has something unique about it....)

Sir Franoys , can i have your tyrannotitan paratype skeleton to fill with muscles and skin ? all credit goes to you.

Of course, however be a little patient because the skeletals are going to be updated very soon. And thank you for asking!

Wonder what the jaw strength of this dino was. We still need a more complete skull to find out though. But it appearently had more robust teeth than its other relatives, so I bet it's jaw strength was a bit stronger.

So it was more or less normally proportioned as opposed to having short legs like in PaleoJoe's skeletal?
Reply

Franoys Featured By Owner Oct 9, 2016
It is one of the possibilities. The images with the scale bars and the measurement tables show important contradictions on the paratype's leg length. I did what i considered most likely, but it is still a possibility that the animal is short legged.

The paratype ha e one of the longest femur recorded in theropoda... 
With such a long femur the short-leg hypothesis (never scientifically proposed) appear out of possibilities

and as it stands, my crude restoration for tyrannotitan came out near identical to this. this is a great relief on my part, as i do aim for my sculpture to be one of the best representations of the species out there.

Interesting restoration.:) (Smile) How did you derive the leg proportions? 
Reply
:iconfranoys:
Franoys Featured By Owner Edited Oct 4, 2016
For the legs, I used the measurements published for MPEF PV 1157 at Novas et al (2005). They stated the femur to be 1,40 meters and the fibula to be less than 70% shorter than that. The size of the tibia and metatarsals are infered of course (the tibias are 10% longer than the fibulas most of the time), based of the size of the fibula and doing some comparisons with giganotosaurus.

The femur length I used at the end somewhat differs from what I got when measuring the bones with the scale bars they provided in the 2013 osteological study. So I decided to trust the figures they gave rather than the results I got when measuring... Scale bars have a higher chance of being innacurate I think. I also compared the two versions of the leg with the mounts (which are mostly composites, but they were based of the real bones), and it seemed like the longer ones fit better.

Even then, it having shorter legs than this is not out of the question.

Ok, so the scale bars I used from Canele et al (2014) are probably inaccurate, but thank you for the insight.

It is not your fault, it was the team which gave wrong measurements, being it the 1st or the second time. Having a 14 cm difference when measuring a femur is just bad.

its still one of the largest theropods but, not as large as T.rex and Giganotosaurus.

That head alone must weight over half a ton. It doesnt look as short legged here as in recent reconstructions, but I guess that comes from the leg bones scaling variations
Reply
:iconfranoys:
Franoys Featured By Owner Oct 4, 2016
I have no idea of the weight of the head right now, but i will do a GDI for this skeletal in the future so we will know. Anyway, Carcharodontosaurid skulls can be tricky, they are long but very narrow and have minimal amounts of bone surface for their size ( they have very big fenestrae holes and airsacs) so they are narrow and "empty". The eye can easily be fooled in lateral view.

True but even then.
Also I see that you implied some nice lower jaw muscles with the black silhouette
